I've been looking at this rafter repair since we moved in 3 years ago. The wife, shorter than I, would like to use this as the master bedroom, but the tie repair bisects the room at shoulder height (I'm just 6ft).
I believe many moons ago there was an insect Infestation and the little beasties munched away at some of the roof, from the outside the roof sags a little. This must of led the rafters to split, hence the repairs. There's a couple of extra 2x4 ties in the loft but higher.
It's not something that I would dare attempt, but I was wondering if it's worth pursuing, maybe approaching an engineer to see if that head cracker can be changed, maybe to a laminated curve? Mega bucks? Probably. I've suspect Mike would confidently have a pop at this Oak in his pyjama's
See what you think, it's just for fun at the moment.

Ps. The window you see is at floor level.
